RS-232 VARIABLE NAMES

"V VARIABLE=VALUE WARNLO WARNHI [DATALO-DATAHI] <CRLF>"

which should reflect the new value. The values in square brackets are not required for all variables. If needed, the values are included on the command line, separated by spaces. For example, to change the instrument ID, the host computer would issue a command like this:

"V MACHINE_ID=1234<CRLF>"

and the CPU should respond with:

"V DDD:HH:MM IIII MACHINE_ID = 1234 (0-9999)<CRLF>"

Table 7.9 lists the variable names which are variable through the RS-232 interface and their corresponding button sequences.
